How much do you know about pistons? Are they truly round? Are they all made of the same material? What's the right way to measure one? Put your knowledge to the test! Modern piston technology is a rabbit hole of engineering, testing, and constant innovation. From materials developments yeilding aerospace-grade coatings, to metallurgical studies constantly evolving the way pistons are forged, machined, and heat treated, it's a never ending cycle.

But when it comes to the slugs you put in your car, how much do you really know about them? Are you an armchair engineer or a bona fide engine master? Take the Wiseco piston quiz below and find out for sure.
